What exactly is [Jeri] building?

[Jeri] put up an awesome tutorial going over the ins and outs of static and dynamic flip-flops. There’s a touch of historical commentary explaining why dynamic registers were used so much in the 70s and 80s before the industry switched over to static designs (transistors were big back then, and dynamic systems needed less chip area). At the end of her video, [Jeri] shows off a bucket-brigade sequencer of sort that goes through 15 unique patterns. We’re just left wondering what it’s for.

Blatant advertising? Yes, but fireballs

Nintendo gave [MikenGary] a Wii U and asked them to make a film inspired by 30 years of Nintendo lore and characters. They did an awesome job thanks in no small part to Hackaday boss man [Caleb](supplied the fire), writer [Ryan] (costume construction) and a bunch of people over at the Squidfoo hackerspace.

Where is the point in connecting a expensive camera with shitty resolution over a serial interface when the Pi has USB and a decent camera (e.g. Logitech C270) comes with HD resolution at half the price?

Because you can, sir, because you can. What’s the fun when you connect something over USB that already works? None: “Yey, this camera works 100% just like it should”. What’s the fun when you connect a shitty camera over serial and build a driver/interface code just to find out that the quality is bad? Priceless: “Yes, I can!”. Shame on you, you shouldn’t be asking that on a website like this xD

He’s obviously never tried to source a PCB camera… You’re lucky to get small 4:3 on a sensor that is plagued with chroma and grain…

What actually matters is price and how many you can source. There are a lot of algorithms that can be implemented even on crappy cameras. Quality doesn’t matter much in pattern matching and vector-diffing…

Because it is the flavor of the month, man. They gotta get all of these Pis out the door for q1 next rev. If you can add useless trinkets that the electronic hobby sites can profit off of, then it is a double win for these guys. Then again ya can just get an old smartphone with more power and features and HD out to tinker with ;) There is indeed a difference between butter and margarine.

For an undisclosed amount of money, you get a large piece of furniture in the shape of the lambda logo that does nothing but turn several hundred kilowatts of electricity into bragging rights for everyone involved.

That’s what those are…… I’ve been looking over a schematic on/off for a year now and couldn’t quite work out the logistics of the Dynamic Flip Flops. I mean I understood the theory (I think) but couldn’t work out why such a design was chosen over the the static FF. I didn’t even realize such terminology existed.
